SICK RLY3-OSSD300 Safety Relay Evaluation Unit (1099969)

The SICK RLY3-OSSD300 is a high-performance safety relay module designed to evaluate safety sensors with OSSD outputs (Output Signal Switching Devices). This compact evaluation unit supports up to 3 enabling current paths, features Category 4 and PL e compliance, and integrates easily with light curtains, safety scanners, and interlock devices requiring reliable relay-based switching.

Engineered for flexible integration and robust performance, the RLY3-OSSD300 features short-circuit-protected semiconductor outputs for diagnostics, along with push-pull output compatibility. It’s ideal for functional safety tasks where SIL 3 protection and rapid response (12 ms) are essential.
